Chalmers Reproservice G¨oteborg, Sweden 2017 Simulation of a Badminton Racket A parametric study of racket design parameters using Finite Element Analysis. Master's thesis in Applied Mechanics ELIAS BLOMSTRAND MIKE DEMANT Department of Applied Mechanics Division of Solid Mechanics Chalmers University of Technology Abstract Badminton, said to be the worlds fastest ball sport, is a fairly unknown sport from a scientific point of view. There has been great progress made to get from the old wooden rackets of the 19th century to the light-weight high performance composite ones used today, but the development process is based on a trial and error method rather than on scientific knowledge. The limited amount of existing studies indicate that racket parameters like shaft stiffness, center of gravity and head geometry affect the performance of the racket greatly. -

Grand Slams’ Are Iconic Global Sports Competitions And, As Proven by the 2017 Australian Open, Capable of Drawing Blockbuster Audiences
The four tennis ‘grand slams’ are iconic global sports competitions and, as proven by the 2017 Australian Open, capable of drawing blockbuster audiences. Roger Federer’s victory over Rafael Nadal brought Eurosport its largest-ever audience for a tennis match with 20.7 million viewers across Europe, while in the host country, the 3.6-million (4.4-million peak) figure was the highest audience for the final in over a decade. The prestige and image attached to grand slam tennis is not lost on the sport’s broadcast partners. For domestic broadcasters this has led to a continuous fee increase for the quartet of slams. Using Sportcal’s Revenue Dashboard – available to subscribers of the Media Intelligence Centre – to analyse the domestic revenue generated, Sportcal Insight examines how the grand slams have enhanced their domestic rights revenues. Currency conversions, where possible, have been done at the time of the deal and modelled data has been used for incremental rises during a rights agreement. All grand slams have long-running domestic deals with established broadcasters. This, it can be argued, limits competition and the potential for mushrooming revenues, resulting in a more modest rise than might otherwise be the case. In Australia, free-to-air network Seven’s most recent deal with Tennis Australia is under investigation by the country’s corporate watchdog because a competitive bidding process wasn’t launched, amid claims that the governing body could have raised an extra A$50 million ($45 million) had the rights been taken to the open market. The 2017 women’s Australian Open final attracted 360,000 more viewers than the final of T20 cricket’s Big Bash League (aired on another free-to-air broadcaster, Network Ten, at the same time). -
TENNIS: History of Tennis at the Olympic Games
OSC REFERENCE COLLECTION TENNIS History of Tennis at the Olympic Games 19.10.2017 TENNIS History of Tennis at the Olympic Games TENNIS Seoul 1988 Beijing 2008 London 2012 Rio 2016 Singles (M) Singles (M) Doubles (W) Singles (M) INTRODUCTION Tennis was on the Olympic programme from the Games of the I Olympiad in Athens in 1896, until the Games of the VIII Olympiad in Paris in 1924. It was then removed from the programme owing to a difference of opinion between the IOC and the International Tennis Federation. Tennis made its Olympic return as a demonstration sport in 1968 and 1984 and has featured on the Olympic programme since the Games of the XXIV Olympiad in Seoul in 1988. KEY STAGES Entry 1894: At the Paris Congress held in June, the desire was expressed for “athletics games (football, lawn tennis, real tennis, etc.)” to feature on the Olympic programme. Withdrawal 1928: At the 27th IOC Session held in Amsterdam in July and August, the IOC Executive Board’s decision to remove tennis from the Olympic programme was approved. This decision was supported following the breakdown in negotiations between the IOC and the International Federation over the latter’s various demands (being able to apply its own definition of amateurism in particular). Return to the 1981: At the 84th IOC Session held in Baden-Baden in September and programme October, it was decided to add tennis to the programme of the Games of the XXIV Olympiad in Seoul in 1988. Mixed doubles 2009: At the IOC Executive Board meeting held in Berlin in August, the addition of mixed doubles for the Games in London in 2012 was approved. -
Rapid Sensory Profiling of Tennis Rackets †
Proceedings Rapid Sensory Profiling of Tennis Rackets † Maximilian Bauer 1,*, Sean Mitchell 1, Nathan Elliott 2 and Jonathan Roberts 1 1 Wolfson School of Mechanical, Electrical and Manufacturing Engineering, Loughborough University, Loughborough LE11 3QF, UK; [email protected] (S.M.); [email protected] (J.R.) 2 R&D Racquet Sports, HEAD Sport GmbH, 6921 Kennelbach, Austria; [email protected] * Correspondence: [email protected]; Tel.: +44-7902-592-659 † Presented at the 13th Conference of the International Sports Engineering Association, Online, 22–26 June 2020. Published: 15 June 2020 Abstract: Tennis racket manufacturers rely on subjective assessments from testers during the development process. However, these assessments often lack validity and include multiple sources of inconsistency in the way testers make subjective ratings. The purpose of this research was to investigate the suitability of the free-choice profiling (FCP) method in combination with principle component analysis (PCA) and multiple factor analysis (MFA) to determine the sensory profile of rackets. FCP was found to be a suitable technique to quickly evaluate the sensory profile of rackets; however, consumer testers tended to use ill-defined, industry-generated terms, which negatively impacted discrimination and inter-rater agreement. Discrimination and inter-rater agreement improved for attributes referring to measurable parameters of the rackets, such as vibration. This study furthers our understanding of tennis racket feel and supports racket engineers in designing new subjective testing methods, which provide more meaningful data regarding racket feel. Keywords: feel; sensory analysis; tennis rackets; free-choice profiling; PCA; MFA 1. Introduction Since performance advancements have become more challenging in the tennis racket industry, manufacturers rely increasingly on consumer feedback in terms of racket feel to provide direction in the development process. -
Ball Change in Tennis: How Does It Affect Match Characteristics and Rally Pace in Grand Slam Tournaments?
Original Article Ball change in tennis: How does it affect match characteristics and rally pace in Grand Slam tournaments? JAN CARBOCH 1 , MATEJ BLAU, MICHAL SKLENARIK, JAKUB SIMAN, KRISTYNA PLACHA Department of Sport Games, Faculty of Physical Education and Sport, Charles University, Prague, Czech Republic ABSTRACT Tennis balls degrade after fast racket and ground impacts until they are changed after agreed number of games. The aim is to analyse the new (after the ball change) and used balls (prior to the ball change) match characteristics and the frequency of rally shots in matches in the Australian Open, French Open and Wimbledon in 2017. Paired samples t-tests and Cohen d were used to compare the point duration, number of rally shots, time between the points, rally pace and work to rest ratio among these tournaments. There was a significant difference in rally shots number played with the new balls (4.17 ± 0.86) compared to the used balls (4.60 ± 1.10) in female matches (p = 0.047); in males matches large effect size was found (d = - 0.83) in the same variable with the new balls (4.44 ± 0.57) and used balls (4.95 ± 0.66), both happened in the Australian Open. No difference was found between the new and used balls in the rally pace in all the observed events. The Wimbledon match characteristics were least affected by the ball change. The ball degradation affected the match characteristic the most in the Australian Open, in terms of more rally shots, but not slowing down the rally pace. -
Tennis Study Guide
TENNIS STUDY GUIDE HISTORY Mary Outerbridge is credited with bringing tennis to America in the mid-1870’s by introducing it to the Staten Island Cricket and Baseball Club. In 1880 the United States Lawn Tennis Association (USLTA) was established, Lawn was dropped from the name in the 1970’s and now go by (USTA). Tennis began as a lawn sport, but later clay, asphalt and concrete became more standard surfaces. The four most prestigious World tennis tournaments include: the U.S. Open, Australian Open, French Open, and Wimbledon . In 1988, tennis became an official medal sport. Tennis can be played year round, is low in cost, and needs only two or four players; it is also suitable for all age groups as well as both sexes. EQUIPMENT The only equipment needed to play tennis consists of a racket, a can of balls, court shoes and clothing that permits easy movement. The most important tip for beginners to remember is to find a racket with the right grip. The net hangs 42 inches high at each post and 36 inches high at the center. RULES The game starts when one person serves from anywhere behind the baseline to the right of the center mark and to the left of the doubles sideline. The server has two chances to serve legally into the diagonal service court. Failure to serve into the court or making a serving fault results in a point for the opponents. The same server continues to alternate serving courts until the game is finished, and then the opponent serves. -

DORAN COMPANY PRINTED IN THE UNITED STATES OF AMERICA APR -I 1921 _ ©CLA611413 « To E. D. K AND M. W. J. MY "BUDDIES" W. T. T. n INTRODUCTION Tennis is at once an art and a science. The game as played by such men as Norman E. Brookes, the late Anthony Wilding, William M. Johnston, and R. N. Williams is art. Yet like all true art, it has its basis in scientific methods that must be learned and learned thoroughly for a foundation before the artistic structure of a great tennis game can be con- structed. Every player who helps to attain a high degree of efficiency should have a clearly defined method of development and adhere to it. He should be certain that it is based on sound principles and, once assured of that, follow it, even though his progress seems slow and discouraging. I began tennis wrong. My strokes were wrong and my viewpoint clouded. I had no early training such as many of our American boys have at the pres- ent time. No one told me the importance of the fundamentals of the game, such as keeping the eye on the ball or correct body position and footwork. -

Shirley Park LTC News Letter – Spring 2012
Shirley Park LTC News Letter – Spring 2012 Club Championships – Summer 2011 Mens Singles Final - Harry Ware beat Dan Hatton 6-1 7-6 It seemed that Harry Ware was in a hurry when he raced through the opening set of the Mens Singles Final against two-time former champion Dan Hatton taking it 6-1 in just 22 minutes. However, the second set proved a much closer affair. Dan struck early on by taking the first two games of a see-saw set that contained some high quality tennis and exciting rallies. Harry then broke service twice to take a 3-2 lead, but Dan returned the compliment and had a chance to take the set when serving at 5-3. Two double faults gave Harry the chance to level and, after sharing service holds, he eased through the tie-break to successfully defend his title in straight sets. Ladies Singles Final - Natalie Davis beat Kamila Morgan 6-2 6-3 This was a tight affair. Kamila came out hitting some crunching forehands but Natalie wisely kept most of her shots to Kamila's backhand in an attempt to neutralise her opponent's game. It became clear early on that Natalie’s strategy was to simply out rally her opponent with her consistency. Natalie showing great resilience broke Kamila in the fourth & sixth games to win the first set 6-2. The second set produced some stunning tennis with Kamlia using her forehand topspin to good effect. Kamila moved into a 3-1 lead and at this stage it looked we could be heading to a third set. -

The First Beautiful Game
THE FIRST BEAUTIFUL GAME Stories of obsession in Real Tennis Roman Krznaric Ronaldson Publications September 2006 CONTENTS Introduction The Wordless Conversation From Abbots to Zealots Life in Court Serving to Gentlemen The Missionary Adventures With My Father References Acknowledgements About the author Notes 2 INTRODUCTION Bent rackets, hand-sewn balls and netted windows. Painted crowns, brass bells and penthouses. Chases, railroads and giraffes. Welcome to the curious world of real tennis. Originating in medieval Europe, the court, rules and equipment have hardly changed in four centuries. Yet this book is not a chronicle of its history, nor is it a manual on technique and strategy. It is about the players and their obsession. Over the past five years I have spoken with real tennis players about their experiences of the sport, why they play and what it means to them. I learned that most of them are fanatics, some are addicts. More than a few are eccentrics. And I found their stories revealing about the art of living: whether to pursue our passions and ambitions, how to balance work and personal life, why we need respect and equality, where we can find and create beauty. This book tells those stories in their own voices. I should admit that I am one of the fanatics, an amateur player who has named three bicycles and a car after former World Champions. I first encountered real tennis in the late 1980s when a student. At the time I was dedicated to another sport that, in my ignorance, I called ‘tennis’ – the game played at Wimbledon and in parks on sunny afternoons.
